1 to 3, FIG. 1 is a schematic block diagram of the motor system of the first embodiment of the present invention, FIG. 2 is a partial enlarged schematic view of the motor system of the first embodiment of the present invention, and FIG. 3 is a diagram of FIG. 2 Perspective schematic. The first embodiment of the present invention provides a motor system 100, which includes: an internal rotation motor device 1 and a cooling device 2 detachably disposed on the internal rotation motor device 1. The motor system 100 may but is not limited to be applied to a motor vehicle, such as a locomotive or an electric vehicle, to provide kinetic energy.

The internal rotation motor device 1 defines a central axis 1a and includes a ring side surface 11 around the central axis 1a. In addition, although the present embodiment is described by using the internal rotation motor device 1 in combination with the cooling device 2, the present invention is not limited to this. For example, in other embodiments not shown in the present invention, the cooling device 2 can also be used alone (for example, sold) or used with other components.

The cooling device 2 is detachably provided on the internal rotation motor device 1 to cool the internal rotation motor device 1. The cooling device 2 includes a flow channel 21, a cooling unit 22 covering the internal rotation motor device 1, a pump 23 connected to the cooling unit 22, and a heat dissipation unit connected to the flow channel 21 twenty four.

The flow channel 21 forms a loop. The flow channel 21 is used for supplying a first fluid and a second fluid to flow in the flow channel 21, and the first fluid can be heated to form the second fluid. That is to say, the difference between the first fluid and the second fluid is only the difference in temperature, and the second fluid is not another fluid that is additionally injected into the flow channel. Through the circuit design of the flow channel 21, the first fluid and the second fluid can cyclically flow in the flow channel 21.

The cooling unit 22 covers the ring side surface 11 of the internal rotation motor device 1 to cool the internal rotation motor device 1. Preferably, a coverage area of the ring side surface 11 covered by the cooling unit 22 is not less than 60% of a surface area of the ring side surface 11 of the internal rotation motor device 1, but the present invention does not Limited by this. With the surface area covering an area of not less than 60%, the cooling unit 22 can provide the internal rotation motor device 1 with a better cooling effect.

The cooling unit 22 includes a fluid inlet 221 and a fluid outlet 222 respectively located at two ends of the cooling unit 22, and the cooling unit 22 is connected to the flow through the fluid inlet 221 and the fluid outlet 222. Road 21. In this embodiment, the fluid inlet 221 and the fluid outlet 222 are along a direction perpendicular to the central axis 1a of the internal rotation motor device 1 (that is, the internal rotation motor device 1 Radial direction), but the present invention is not limited to this.

The cooling unit 22 can absorb the heat of the internal rotation motor device 1 through the first fluid flowing through the cooling unit 22, so that the first fluid is heated to form the second fluid, according to The temperature of the internal rotation motor device 1 is lowered. In other words, the internal rotation motor device 1 transfers its heat to the first fluid through the cooling unit 22, so that the temperature of the internal rotation motor device 1 can be effectively reduced.

It is worth mentioning that the first fluid is mainly used to absorb the heat of the internal rotation motor device 1. Therefore, as long as the heat of the internal rotation motor device 1 can be effectively absorbed, the present invention does not limit the selection of the material of the first fluid. For example, the first fluid in this embodiment may be water, or other fluids with a thermal conductivity of not less than 0.6 W/m°K, but the present invention is not limited thereto.

In this embodiment, the cooling unit 22 is preferably made of a high thermal conductivity material, and the thermal conductivity of the high thermal conductivity material is greater than 1 W/m°K, but the present invention is not limited to this. By selecting the high thermal conductivity material with a thermal conductivity greater than 1 W/m°K, the cooling unit 22 can provide a better cooling effect.

In this embodiment, the cooling unit 22 is illustrated by a water bag 22a, but the present invention is not limited to this. The water bag 22a includes two wide sides on opposite sides, and is adjacent to one of the wide sides of the internal rotation motor device 1 to detachably cover the internal rotation motor device 1 Ring side 11. Accordingly, the water bag 22a can cover the ring side surface 11 without winding the central shaft 1a of the internal rotation motor multiple times (for example, winding the central shaft 1a only once), so that the The cooling device 2 can be conveniently arranged on the internal rotation motor device 1 or separated from the internal rotation motor device 1.

The pump 23 communicates with the cooling unit 22 through the flow channel 21. The pump 23 can be used to make the first fluid flow into the cooling unit 22 from the fluid inlet 221 and can be used to make the second fluid flow out of the cooling unit 22 from the fluid outlet 222. It should be noted that the pump 23 is mainly used to accelerate the flow of the first fluid and the second fluid, but the present invention does not limit the form of the pump 23.

The heat dissipation unit 24 is connected to the flow channel 21. The heat dissipation unit 24 is used to absorb the heat of the second fluid to cool the second fluid to form the first fluid. After the second fluid is cooled to form the first fluid, the first fluid flows into the cooling unit 22 from the fluid inlet 221. After the first fluid absorbs the heat of the internal rotation motor device 1 to heat up to form the second fluid, the heat dissipation unit 24 absorbs the heat of the second fluid again to cool the second fluid The first fluid is formed. By continuously cooling the second fluid with a higher temperature to the first fluid and allowing the first fluid with a lower temperature to flow into the cooling unit 22 from the fluid inlet 221, the cooling unit 22 can The temperature of the internal rotation motor device 1 is continuously lowered.

The heat dissipation unit 24 mainly provides a heat dissipation effect, but the present invention does not limit the manner in which the heat dissipation unit 24 provides a heat dissipation effect. For example, the motor system 100 may be installed in an electric locomotive, and the heat dissipation unit 24 may be an air-cooled heat dissipation unit. When the electric locomotive is driven, the air-cooled heat dissipation unit can provide a better heat dissipation effect through the moving electric locomotive.
